Lana, a regular reader of Viva Woman, left me a question asking if mineral makeup expire or go bad and I thought it’s a good question which warrants a blog post.
If you’re a user of mineral makeup, you should have noticed that most brands indicate that their mineral makeup have an indefinite shelf life because:
- they are made from inorganic ingredients that contain inert minerals
- the inorganic ingredients cannot support microbial growth
- they contain no moisture and bacteria cannot form and thrive
- they do not use preservatives, fillers or synthetic dyes.
